I hit a small geometry bug in IsPointOnArc() and in working on it started
to wonder about a couple things:

* are non-circular arcs needed yet?  IsPointOnArc() says its broken for
them but I don't know if we care since I didn't see how to make them in the
interface.  But I thought I heard some talk about them recently.  IIRC even
e.g. the toporouter doesn't use them

* do we care about arcs with square ends?  They have ANYOBJECTFIELDS so
could in theory
  have this but I don't see the point, since unlike lines they aren't used
to represent pads.  And it
  takes another check against an off-axis rectangle

Fixing the the other bug in this fctn (arcs thicker than their radius) is
about done also
